Nokia Registers - Home Subscriber Server (HSS)

Most operators today have to deal with different technologies in their networks, be they fixed, mobile, 2G, 3G, 4G, 5G or WiFi networks. They need to manage subscribers’ data and subscriber access management in a flexible way across all these technologies, while also delivering a high-quality of service to their subscribers and ensuring quick and smooth introduction of new and innovative services. Nokia Registers offers a future-proof, unified access management solution for all domains.

Nokia Registers is an advanced, unified solution for comprehensive subscriber access and data management across diverse network technologies. It represents the evolution of Nokia's industry-leading Home Subscriber Server (HSS) and integrates the functionalities of Home Location Register (HLR), HSS, Unified Data Management (UDM), and Authentication Server Function (AUSF) into a single, cloud-native platform. This comprehensive offering is further enhanced by Nokia Advanced Registers, which delivers next-generation capabilities for optimized network operations and lifecycle management. 

Using the advanced capabilities of Nokia user data repositories (One-NDS / Shared Data Layer (SDL)), Nokia Registers solution enables subscriber data to be consolidated into a common repository using a distributed and flexible architecture.

• The Nokia Registers solution supports management of 2G, 3G, 4G, 5G, IoT and fixed networks in a unified and extremely scalable approach that decouples subscriber data management from HLR/HSS/UDM/AUSF functions.

• The Nokia Registers is a powerful solution for multi-technology network subscriber data and service management, and is ready for evolution to 5G and upcoming next generation networks.

Nokia Registers is crucial for operators navigating the complexities of multi-generational and multi-access networks. It unifies critical subscriber management functions, ensuring seamless operation and efficient evolution.

Unified Functionality: Nokia Registers consolidates key network functions:

• UDM (Unified Data Management) & AUSF (Authentication Server Function): Essential for 5G subscriber data and authentication, enabling standards-compliant data management.
• HSS (Home Subscriber Server): Provides subscriber data management for LTE and IMS networks.
• HLR (Home Location Register) &  AuC (Authentication Center): Manages 2G/3G subscriber access and authentication.

Cloud-Native Architecture: As a cloud-native solution, Nokia Registers offers a flexible and agile architecture, allowing operators to choose optimal deployment scenarios and scale resources dynamically.

Centralized Data Management (SPR): The Subscriber Profile Repository (SPR) within Nokia Registers facilitates the centralization of third-party Policy and Charging Rules Functions (PCRF) data into the highly scalable and geo-redundant One-NDS platform, simplifying policy enforcement and data consistency.

Operational Simplification: By integrating these diverse functions, operators can reduce complexity, streamline operations, and accelerate the deployment of new services across their entire network footprint.
